The composition oflithium bhatiri
Iko kuumbwa kwezvinhu zvemabhatiri e lithium kunonyanya kusanganisira zvakanaka electrode zvinhu, negative electrode zvinhu, separators, electrolytes, uye casings.
- Pakati pezvinhu zvakanaka zve electrode, iyo inonyanya kushandiswa zvinhu ndeye lithium cobaltate, lithium manganate, lithium iron phosphate uye ternary zvinhu (polymers nickel, cobalt uye manganese).Iyo yakanaka electrode zvinhu inoverengera chikamu chikuru (huwandu hwehuwandu hwezvakanaka uye zvisina kunaka electrode zvinhu ndeye 3: 1 ~ 4: 1), nokuti kushanda kweiyo yakanaka electrode zvinhu zvinokanganisa zvakananga kushanda kwe lithium-ion bhatiri, uye mutengo wayo unotarisawo zvakananga mutengo webhatiri.
- Pakati pezvinhu zvakashata zve electrode, magirafu echisikigo uye magirafu ekugadzira pari zvino ndiwo makuru asina kunaka emagetsi emagetsi.Anode zvinhu zviri kuongororwa zvinosanganisira nitrides, polyaspartic acid, tin-based oxides, tin alloys, nano-anode zvinhu, uye mamwe intermetallic komisheni.Sechimwe chezvinhu zvina zvikuru zvemabhatiri e lithium, zvinhu zvisina kunaka zve electrode zvinoita basa rakakosha mukuvandudza bhatiri uye kuita kutenderera, uye zviri pakati pekusvika kwepakati peiyo lithium bhatiri indasitiri.
- Zvigadzirwa zvediaphragm zvemusika zvinonyanya kuve polyolefin diaphragms, ayo anonyanya kugadzirwa nepolyethylene uye polypropylene.Muchigadziro che lithium bhatiri separator, muparadzi ndechimwe chezvinhu zvinokosha zvemukati.Kuitwa kwemuparadzi kunogadzirisa chimiro chekugadzirisa uye kupikisa kwemukati kwebheteri, iyo inobata zvakananga kukwanisa, kutenderera uye kuchengetedza kushanda kwebheteri.Muparadzi ane mashandiro akanaka anoita basa rakakosha mukuvandudza kuita kwebhatiri rese.
- Iyo electrolyte inowanzo gadzirwa nepamusoro-kuchena organic zvinonyungudutsa, electrolyte lithium munyu, zvinodikanwa zvekuwedzera uye zvimwe zvinhu mbishi mune chimwe chikamu pasi pemamwe mamiriro.Iyo electrolyte inobata basa rekuitisa maion pakati peyakanaka uye isina kunaka maelectrode e lithium bhatiri, inova vimbiso yekukwira kwevoltage uye yakakwirira chaiyo simba re lithium ion bhatiri.
- Battery casing: yakakamurwa kuita simbi casing, aluminium casing, nickel-plated iron casing (yecylindrical mabhatiri), aluminium-plastiki firimu (soft packaging), nezvimwewo, pamwe nebhatiri chivharo, inova zvakare yakanaka uye yakaipa materminal bhatiri
- Nheyo yeBattery basa
- Kana bhatiri rachajwa, lithium ions inogadzirwa pane yakanaka electrode yebhatiri, uye inogadzirwa lithium ion inoenda kune iyo yakaipa electrode kuburikidza ne electrolyte.Iyo kabhoni chimiro cheiyo negative electrode ine ma pores akawanda, uye lithium ions inosvika kune yakaipa electrode yakaiswa mukati meiyo micropores yekabhoni layer.Iyo yakawanda lithium ions yakavharidzirwa, iyo yakakwirira yekuchajisa ichave.Kana bhatiri ichibudiswa, lithium ions yakaiswa mu carbon layer ye negative electrode inobuda uye inodzokera kune yakanaka electrode.Iyo yakawanda lithium ions iyo inodzokera kune yakanaka electrode, iyo inowedzera simba rekubuda.Kazhinji kutaura, simba rekubuda rinoreva simba rekubuda.Panguva yekuchaja uye kuburitsa kwe lithiamu bhatiri, lithium ions iri mumamiriro ekufamba kubva kune yakanaka electrode kusvika kune negative electrode.Kana mufananidzo we lithium bhatiri inofananidzwa nechigaro chinozunguza, migumo miviri yechigaro chinozunguza ndiyo yakanaka uye isina kunaka electrode yebhatiri, uye lithium ions yakafanana nevatambi, vachimhanya vachidzoka nekudzoka pakati pemigumo miviri yechigaro chinozunguza. .Saka lithium mabhatiri anonziwo rocking chair mabhatiri.
